I have an RPi 3 and want to attach a scope to the physical Tx and Rx lines for Ethernet. I noticed on the back of the PCB near the Ethernet connector, there's test points labeled "PP52" - "PP57" which seem to connect to the Ethernet connector pins.

Does anyone know the correlation between these test points and the standard Ethernet pinout?

Thanks!

I don't know which is which but they should be easy enough to figure out.
Note that the connector box is not a straight pass through. There are components inside the shell.
See schematic page 3 at grid location J-3: https://www.raspberrypi.org/documentati ... matics.pdf
Note this is schematic for old B model but should be very similar.
